505.20/.30 HPU Connections
Installation
Connecting the
controller cable
Note If a controller is not used, the installed jumper plug must be used or the
unit will not start.
• The controller cable provides a means to connect your controller to the
HPU.
• The controller cable allows you to remotely start and stop the unit and
switch between the low and high pressure selections. The controller cable
also permits the controller to monitor the low level, over temperature, and
dirty filter status.
Connect the controller cable to the connector located at the lower left side of the
electrical enclosure.
Connecting electrical
service to the HPU
Important Local electrical codes supersede any information found here.
• Electrical connections must be made by qualified personnel and conform to
local codes and regulations.
• The electrical box has a power disconnect switch that must be off (O) in
order to open the electrical box.
• An electrical service panel to provide the electrical power feed (line voltage)
to the HPU is not necessary, but may be required by local electrical codes.
1. Connect the three electrical power feed wires to the input lugs of the power
disconnect in a counterclockwise phase orientation as indicated by the L3,
L2, and L1 labels shown in the next figure (the Model 505.20/.30 high
voltage configuration is shown).
